30 psi on outer edges. </font></font><font size="+1"><font
face="Gill Sans MT">I've been looking at two products: Unifoam
25/30 and Plastifab 25/30. Aiming for R35 under the slab. Price
differential is significant (Unifoam is nearly $3000 more) for
the house. <br>
</font></font></p>
<p><font size="+1"><font face="Gill Sans MT">Has anyone had
experience with either product? From the specs, Unifoam
appears to absorb less water and has less deflection, but both
are within the ASTM spec for the issue. <br>

insights!</font></font></p>
